After popping out Data Explorer, columns do not always populate in filter dropdown

Hi,

I've had this issue come up quite often especially if I "pop out" the data viewer. When I try to filter in the custom sort, I don't see variables listed. Sometimes when I scroll, the list will refresh, but not always.

Does anyone else get this issue?

I also can reproduce this, although the list does refresh for me if I scroll:

This is easily reproduced.

It's some kind of a layout / timing issue because every 10-20 times the column selector dropdown is shown, it will work properly. I'm investigating what's going on.

@softwarenerd Can we please move this out of the 2025.09 milestone?
